A secured SDN framework for IoT

In the last couple of years Software Defined Network (SDN) have come into existence which empowers network operators with more flexibility to manage and program their network. This type of network solves the limitation of legacy networks. Data plane and control planes are separated from each other as a result data plane devices simple act as a packet forwarding device and leaving the decision making part to a centralized system called controller. Though it has a lot of advantages, still security of SDN is an open issue. In modern day living wireless sensor network (WSN) technologies come across all most all areas which creates another research dimension called IoT where sensors and actuators blend in one piece. Application of SDN architecture in the IoT environment is a higher challenge. In this article we will present the security challenges in SDN and a secured architecture for IoT in an SDN based network.
